BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic structural view of the present invention.

(2) FIG. 2 is a side view of the hinge of the present invention.

DETAILED DESCRIPTION

(3) To make the objects, technical solutions and advantages of the present invention clear, the followings will describe the present invention in detail using specific embodiments with reference to the drawings.

(4) As shown in FIGS. 1 and 2, the refrigerator (not shown in the drawings) of the present invention comprises a cabinet (not shown in the drawings), a door (not shown in the drawings) and a hinge 100 for connecting the cabinet and the door.

(5) The door comprises a shaft sleeve (not shown in the drawings) to cooperate with the hinge 100.

(6) The hinge 100 comprises a fixing plate 1, a supporting plate 2 perpendicularly connected with the fixing plate 1, and a hinge shaft 3 perpendicularly mounted on the supporting plate 2 to cooperate with the shaft sleeve.

(7) The fixing plate 1 is provided with three screw holes 11.

(8) The supporting plate 2 is provided with a mounting hole 21 for mounting the hinge shaft 3 which is to be inserted into and fixed in the mounting hole 21. In the present embodiment, the hinge shaft 3 passes through the mounting hole 21 and is fixed on the supporting plate 2 by a rivet. Of course, the hinge shaft 3 may be fixed on the supporting plate 2 in other manners.

(9) The outside of the hinge shaft 3 is plastic-encapsulated with a plastic encapsulating case 31 which can prevent corrosion of the hinge shaft 3 and increase the structural strength thereof. The thickness at respective parts of the plastic encapsulating case 31 may be adjusted according to the machining errors and surface roughness of the hinge shaft 3 to correct the perpendicularity of the hinge shaft 3, thereby avoiding poor alignment of the door.

(10) The plastic encapsulating case 31 is provided with a protrusion 311 protruding horizontally outwards along the extension direction of the supporting plate 2, and the protrusion 311 is integrally formed with the plastic encapsulating case 31. The protrusion 311 can reduce the contact area between the hinge shaft 3 and the shaft sleeve to reduce the frictional force therebetween, reduce the fitting clearance between the hinge shaft 3 and the shaft sleeve, and avoid radial shaking of the door.

(11) Two protrusions 311 are arranged on the plastic encapsulating case 31, and are respectively arranged on the two sides of the supporting plate 2 in the height direction of the hinge shaft 3. Of course, the protrusions 311 may be arranged only on one side of the supporting plate 2, or two protrusions 311 may be arranged on each side of the supporting plate 2 according to the needs to further reduce radial shaking of the door.

(12) The protrusion 311 protrudes outwards in a ring shape and comprises an abutting portion 3111 to cooperate with the shaft sleeve in an abutting manner and a transition zone 3112 connecting the abutting portion 3111 and the plastic encapsulating case 31 in an arc shape to reduce the cooperation difficulty between the shaft sleeve and the hinge shaft 3. The maximum outer diameter of the abutting portion 3111 is equal to the inner diameter of the shaft sleeve.

(13) According to the hinge 100 of the refrigerator of the present invention, on one hand, the plastic encapsulating case 31 is plastic-encapsulated outside the hinge shaft 3, so that the hinge shaft 3 is isolated from air and corrosion of the hinge shaft 3 can be prevented. On the other hand, the thickness at respective parts of the plastic encapsulating case 31 may be adjusted according to the machining errors and surface roughness of the hinge shaft 3 to correct the perpendicularity of the hinge shaft 3, thereby avoiding poor alignment or flash clearance of the door. Further, as the ring-shaped protrusion 311 is arranged on the plastic encapsulating case 31, the contact area between the hinge shaft 3 and the shaft sleeve is reduced to reduce the frictional force and the fitting clearance therebetween and avoid shaking of the door. Therefore, according to the hinge 100 of the present invention, the above effects can be realized only by plastic-encapsulating the plastic encapsulating case 31 outside the hinge shaft 3. The hinge is simple in structure and economical in cost, and is therefore worthy of being promoted.

(14) The above embodiments are intended to illustrate rather than limit the technical solutions of the present invention. Although the preferable embodiments describe the present invention in detail, those skilled in the art shall understand that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope thereof.
